Research | Current

My research focuses on the synthesis of organic molecules and whilst doing so exploring fundamental chemical principles to aid the development of efficient synthetic methods, the preparation of novel molecular structures and to answer complex biological questions.

At present my research group is working on number of different research areas including, the development of new synthetic methodologies enabling he preparation of DNA-binding molecules, the synthesis of bioactive lignans (plant derived natural products) and the synthesis of complex alkaloids as novel treatments for dementia and cancer. Along with this my research group is active in the development of new synthetic methods to prepare organic molecules rich in heteroatoms, such as nitrogen, oxygen and sulfur. I also am active in a number of national and international multidisciplinary research projects working on areas such as the development of new polymeric materials, natural product synthesis and determination and the synthesis of labelled wine components for wine profiling.


My current research focuses on numerous areas including

  • Synthesis of 1,4-benzodioxane lignans biological active and have a wide range of activites including cytotoxicity, acting as alpha-or beta-blocking agents useful in antidepression or antihypertension therapy.
  • Synthesis of bioactive heterocycles such as thieno- and furano-pyridines. These compounds have been shown to inhibit a number of important enzymes involved in cell regulation and are being analysed for their anticancer activity.
  • Synthesis of complex dineolignans, which have wide ranging biological activities including HIF-1 inhibition (an anticancer target) and neuroprotective properties.
  • Synthesis of novel heterocyclic frameworks based on substituted pyrroles.
  • Synthesis of complex bioactive marine natural products that contain substituted pyrroles. Current molecules of interest are: Trikentramine, the Mukanadins, Lamellarins and Kottamides
  • Synthesis and modulation of bioactive compounds derived from grape material
  • Synthesis of novel polymeric materials including advanced conducting polymers
  • Synthesis of isotopically labelled natural products for use in quantitative analysis
  • Synthesis of novel antibacterial materials from renewable, bio-based, sources
